Scope
What we test in Benton County
Concrete testing services
Fresh concrete sampled and tested at the pour — slump, air content, unit weight, and temperature — with cylinders and beams cast on site and broken in the laboratory on the schedule your specification calls for.
ASTM C172ASTM C143ASTM C231ASTM C173ASTM C138ASTM C1064ASTM C31ASTM C39
Aggregate testing services
Gradation, fines content, specific gravity and absorption, unit weight, abrasion resistance, and stockpile moisture for concrete, base course, and backfill aggregates.
ASTM D75ASTM C136ASTM C117ASTM C127ASTM C128ASTM C29ASTM C131ASTM C566
Soil compaction and density testing
Standard and modified Proctor curves in the laboratory and in-place density by nuclear gauge on every lift, so fill, subgrade, and trench backfill are documented against the specified percent compaction.
Soil classification and index testing
Sieve and hydrometer gradation, Atterberg limits, moisture content, specific gravity, and USCS classification for earthwork acceptance, select-fill verification, and geotechnical reports.
ASTM D6913ASTM D7928ASTM D1140ASTM D4318ASTM D2216ASTM D854ASTM D2487
Soil corrosivity testing
pH and electrical resistivity of backfill for MSE walls, pipelines, and buried structures, reported against the specification limits for metallic and geosynthetic reinforcement.
Special inspection (IBC Chapter 17)
ICC-certified special inspectors for reinforced concrete and soils, reporting to the building official alongside the materials test results, so one agency covers both requirements.

Local conditions
Construction materials testing conditions in Benton County
Benton County is one of the fastest-growing counties in Arkansas, with sustained residential subdivision development, commercial corridor build-out along U.S. 412 and I-49, and expanding public infrastructure throughout Rogers, Bentonville, and Siloam Springs. The Ozark Plateau geology underlying much of the county means contractors and geotechnical teams regularly encounter shallow rock, variable residual soils, and karst-influenced conditions that demand precise soil classification and compaction verification rather than assumptions. Concrete placement in northwest Arkansas also has to account for a climate that delivers both summer heat — which accelerates set times and affects air content — and late-season cold fronts that can compromise early-age strength gain. Our certified technicians, dispatched from a regional hub, provide ASTM-compliant field and laboratory testing of concrete, aggregate, and soil to give engineers and contractors defensible data at every phase — from earthwork through final structural pours — backed by a laboratory operating under a documented quality system.
Northwest Arkansas soils derived from Ozark chert and limestone residuum can vary sharply in plasticity and bearing character across short distances, making soil classification (ASTM D2487) and compaction curve development (ASTM D698/D1557) especially important for foundation and pavement subgrade work. Concrete scheduling in Benton County should account for the region's freeze-thaw season — typically November through March — where ACI 306R cold-weather concreting practices become directly relevant to cylinder curing procedures and strength acceptance.
FAQ · Benton County
Our project is in Bentonville and involves a heavily chert-laden subgrade. Can you classify those soils and develop a valid compaction curve for that material?
Yes. Chert-rich residual soils common to the Ozark Plateau are classified under ASTM D2487 (Unified Soil Classification System). When oversized particles are present, ASTM D698 or D1557 compaction testing requires corrections per ASTM D4718 for oversize fractions. Our technicians document material character and apply the appropriate procedure so the compaction curve reflects what is actually placed in the field.
Benton County has seen a lot of large warehouse and distribution center construction. What concrete testing is typically required for those tilt-up and slab-on-grade pours?
Large slab and tilt-up pours typically require fresh concrete testing per ASTM C172 (sampling), C143 (slump), C231 or C173 (air content), C1064 (temperature), and C138 (unit weight), with compressive-strength cylinders cast per ASTM C31 and broken at project-specified intervals per ASTM C39. Our technicians follow ACI Field Testing Technician certification protocols and document every test in a format structured for engineer review and owner records.
We're placing concrete footings in late October. What precautions affect how you collect and handle cylinders on a Benton County project?
Once ambient or concrete temperatures approach 40°F, ACI 306R cold-weather provisions apply. Field cylinders must be protected from freezing during the initial 24-hour curing period; ASTM C31 specifies acceptable initial curing temperature ranges. Our technicians document ambient and concrete temperatures at time of casting and note any cold-weather protection measures in place, which supports the contractor's ACI 306R compliance record.
How fast can a technician be on site in Benton County?
Benton County work is dispatched through our Kansas City, MO regional hub. Scheduled visits are set up by phone at (346) 420-5425; multi-day placements and full-time project assignments are scheduled through a proposal request.
Which office covers materials testing in Benton County, AR?
Field work in Benton County is dispatched through the Kansas City, MO regional hub, about 190 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Benton County projects.
Are the technicians you send to Benton County certified?
Yes. Concrete technicians hold ACI Concrete Field Testing Technician Grade I; soils and laboratory technicians hold NICET Construction Materials Testing certifications; special inspection is performed by ICC-certified special inspectors. Where Arkansas agencies or owners require state-specific certifications, those are confirmed in the proposal.
